- SPECIFICATION forming part of Letters Patent No. 607,515, dated July 19, 1898.

Application filed March 29, 1897. Serial No. 629,692. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM E. LEONARD and CHARLES O. HEsooX, of Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Dish WVashers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to certain improvements in dish-washing machines, the object being to provide a machine for this purpose which shall be capable of receiving a large number of dishes, table-cutlery, and similar articles to be washed and which is so designed that they shall be quickly and thoroughly cleansed by the use of a small quantity of water.

To these ends our invention comprises certain novel features of construction and an rangement of parts whereby the above and other important advantages are gained, as will be hereinafter fully described, and specifically defined in the appended claims.

In the accompanying drawings, Figure 1 represents a perspective view of a dish-washing machine constructed in accordance with our invention. Fig. 2 is a vertical section thereof. Fig. 3 is a detail plan view of a tray used in connection with our invention. Fig. 4 is a vertical section on the line 4: 4: of Fig. 3, and Fig. 5 is a detail View of a cage used in connection with our invention to hold outlery and other small articles.

Similar reference-numerals indicate corresponding parts in all the figures of the drawings.

1 represents a vessel,shown as cylindrical in form, provided at its top with a hinged cover .2 and with an inverted conical bottom 3, through which an opening is made which leads to a catch-basin 4, securely fastened thereto. The catch-basin 4 is provided with an outletpipe 5 for the discharge of the dirty water and with a central vertical column 5, which extends up through the opening in the bottom into the vessel 1, and the said column is hollow and receives within it a rod 7, which is threaded at its upper end to engage a threaded opening in the upper end of the sleeve 8, which is adapted to move upon the column 5, the lower end of this sleeve 8 being provided with an inverted conical cup 9, which we term the dasher, which may be cast in one therewith and which is intended to normally rest upon the inner face of the bottom 3.

A series of splayed or tapering holes are formed in the cup 9, the largest diameter of which being upon the outside, and the purpose of these holes is to force the water upwardly among the dishes as it descends in the water contained in the vessel during the process of washing, as well as to permit the dirty water to drain through into the catchbasin above referred to.

Arranged within the vessel and in close proximity to the bottom thereof is a dish-receiving device 10, which we termthe tray, which consists of a series of circular wires supported in fingers 11, arranged upon a series of radial arms 12, which when properly arranged form suitable supports to receive and hold the dishes in place. lVe use in connection with this tray a cage 13, divided into a series of vertical compartments adapted to receive the cutlery or other small articles which could not be conveniently arranged upon the tray, and this cage is preferably formed of wire mesh, being subdivided by a wire 13, which extends partially around and into the body of the cage. This cage is closed at the bottom and open at the top to receive the cutlery, as will be apparent.

A series of arms or supports are arranged upon the outer wire of the tray, and these serve to hold bowls or other deep dishes which cannot be conveniently arranged between the wires of the tray.

The rod 7 is provided near its lower extremity with an opening 7, which, receives within it one end of a lever 1 1-, and the intermediate portion of the rod is pivotally connected to alink 1 1, pivoted to the under side of the inverted conical bottom 3, and the opposite end of this rod is pivotally connected to a bar 15, which moves within suitable guideways 15, formed on a bracket 16, secured to the vessel 1.

lhe bracket 16 is provided with an extension 17, which projects beyond the upper edge of the vessel 1, being provided with a bearing 17 for the support of the shaft 17", which carries on one end a cam 18 and upon its other end a crank 19, which latter is operated by the handle 19 to move the cam above referred to.

The upper end of the bar 15 is provided with an antifriction-block, which bears upon the edge of the cam and serves to give freer movement thereto, and a spring 20 is arranged upon the rod 7, which serves to keep it normally lowered, in which position the outer end of the rod 1 1 will be lifted soas to move the bar up and bring its antifrictionblock to bear against the cam, as clearly shown.

It will be observed by reference to the drawings that the cam is so constructed that by a rotation of the handle the bar 15 will be slowly lowered, so as to cause the dasher 9 to rise slowly in the vessel until the largest part of the cam has been brought to bear upon the upper end of the bar 15, when the abrupt termination of the volution of the cam-surface at 18, through the action of the spring and the lever 14-, will cause the arm to suddenly fall, moving the dasher through the water in the vessel and forcing it up among the dishes.

The bottom 3 is provided with a series of sockets 21, shown as three in number, for the reception of a corresponding number of legs or supports 22, which may be held together by rungs 23 or in anyother desired orconvenient manner,and the outlet-pipe leading from the catch -basin is provided with a suitable faucet to close it during the operation of washing dishes.

\Vhile we have described our invention as cylindrical in form, it must be understood that the vessel may be square, rectangular, or any other desired form and the parts arranged to suit the requirements, and we reserve the right to make these changes and such others as may come within the spirit and scope of our invention.

It will thus be seen that our invention provides in a very simple and inexpensive manner a dish-washin g machine which is particularly well adapted for the purposes for which it is intended, which is simple in construction, which by reason of dashing the water among the dishes in the manner described effectually removes the dirt therefrom, and that by providing the dasher with a series of perforations the water will be forced up among the dishes and afterward readily drain through into the catch-basin, leaving comparatively clean water at all times above the dasher.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A machine for washing dishes, comprising a vessel having a conical bottom with a catch-basin attached to the lower central portion thereof havingan openingtherethrough,

a tray arrangedwithin said vessel, adapted to hold the dishes, a cage arranged upon said tray to receive cutlery and internally divided by an upwardly-projecting portion, a perforate inverted conical dasher below the said tray and cage, conforming to the shape of the botto1n,and a rod extending upwardly through the catch-basin and bottom of the vessel and the dasher for operating the latter, substantially as described.

2. A machine for washing dishes, comprising a vessel, a tray arranged within said yes sel, composed of a series of circular wires supported in fingers arranged upon a series of radial arms and adapted to hold said dishes, a compartment-cage arranged upon said tray to receive cutlery, and a perforated dasher arranged below said cage, and means to operate said dasher to force the water on the dishes and cutlery,substantially as described.

3.
